I am using ubuntu 20.10
My device memory got full in just 10 days from 250 gb to 100 gb
when i looked into logs i found kern.log file which has a storage of about 50 gb
I looked into many solutions but none of them seems to be working for me .
I get errors like below

We have two hypervisor(Dell PowerEdge R630, virtualization environment: Proxmox), they are connected with an FC-switch and the FC-switch with the storage(dell compellent).
One of the hypervisor are connected via multipath to the storage and it's works.
The other hypervisor doesn't found the storage.
The not-finder-hypervisor says:

Today, I have noticed that unicorn was not running on the production environment. Unicorn error log is as follows (it seems unicorn stopped due to SIGKILL signal):
D, [2017-10-11T12:25:49.521336 #9375] DEBUG -- : waiting 16.0s after suspend/hibernation
E, [2017-10-11T12:26:08.051349 #9375] ERROR -- : reaped #<Process::Status: pid 9535 SIGKILL (signal 9)> worker=1
I, [2017-10-11T12:26:21.708135 #9375] INFO -- : worker=1 spawning...
It seeems when the unicorn was killed, we had faced a out of memory problem. In the /var/log/syslog.1 I have following logs:
Oct 11 12:26:02 analiz kernel: [4486147.309450] [<ffffffff81190979>] out_of_memory+0x219/0x460
Oct 11 12:26:02 analiz kernel: [4486147.309677] Out of memory: Kill process 9375 (ruby2.3) score 81 or sacrifice child
Now my questions are;
How I can make sure that unicorn will be restarted automatically even if it gets killed by kernel? (eg, restart automatically after 30secs)
In the normal operation, memory utilization is around %50-%60. I would like to understand the root cause and take measures to prevent a similar problem in future. According to the syslog messages, out of memory issue is started with postgres. I have no clue what caused a high memory utilization by postgres or other processes. Any kind of support will be appreciated.

How can I go about the migration path 1.4 to 1.5, and how to deal with that error above?
As the log file states, "Cannot upgrade TokuDB version 25 database. Previous improper shutdown detected."
TokuMX does not support upgrades (meaning the file format has changed) unless the files you are using from the prior version came from a cleanly shutdown TokuMX.
You need to cleanly shutdown your 1.4 server, then copy or re-use the data files with 1.5.
I'm doing a app like photo browser just like the "Photo" on iTOuch. And I use a third-party lib : https://github.com/kirbyt/KTPhotoBrowser
When I scroll the photos several times, the app crashes.
The log shows that it has receive memory warning.
Then I use instrument to check the memory (I choose Memory-Allocation).
I track the Live Bytes and Overall Bytes for "All Allocations".
However, the Live Bytes is never more than 5 MB, and the Overall Bytes is beyond 100 MB .
When the app carshes, the Live Bytes is 3.97MB and the Overall is 125.48MB.
I think Live Bytes is the memory currently used, and it seems it costs a little.
Why the app still crashes?
Xcode 4.2 4D199,Lion 10.7.2(11c74), iTouch ios5.0.1 beta2.
Below is the screenshot, and the instrument configuration is the default.
Any idea?
the crash log is like:

It is my own fault!
when I use NSURLConnection to detect the MIME-TYPE of the file, the memory of the connection is never released and it becomes larger and larger(As I detect the type of more than 100 files).
I reconstruct the code.
